Lute,

The RS232 pak requires high signal on DTR, CD and I think CTS before it will
listen to a thing being sent to it.

Depending on the modem, you can either flip a few dips or send a few commands
to accomplish this task. My Hayes 2400 baud modem handles the task nicely with
the command string of AT &C0 &D0.

Older style modems have a switch you can filp to accomplish the same thing.

Real old modems require a jumper of pins 6-8-20 on the cable.

You might want to peruse Pete's disertation on serial communications in DL1
called SERIAL.TXT. It might shed some light.

Steve
